* build: sort sources to build in a more deterministic wayPhilippe Coval2015-01-051-1/+1
| | | | | | | | | | | | | | | | | It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible.

| * Makefiles: don't include *.tmpH. Peter Anvin2014-01-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since checkin: bd09a6d828fa Major Makefile cleanups; gcc 4.3.0 compatiblity ... we include *.tmp into the Makefiles as well as .*.d. This seems to have been a mistake in made when adding *.tmp to cleanup rules, probably using a sed script. This causes problems, because *.tmp files are generated by the gcc_ok macro and do not contain Makefile rules at all. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
* | mk/embedded.mk: Don't use -mregparm in coreMatt Fleming2013-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately commit 4eb06d95d882 ("mk: Add -fPIC for x86_64 to embedded.mk") left -mregparm enabled when compiling objects in core/, which means that when compiling for i386 those objects are compiled with a different ABI compared with everything else, leading to hangs when booting under 32-bit EFI. We should only enable -mregparm for code that absolutely requires it, such as dos/crt0.S which would need to be re-written to use another ABI. Signed-off-by: Matt Fleming <matt.fleming@intel.com>
* | Add per-firmware object directory supportMatt Fleming2012-10-161-7/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that we have multiple firmware backends it no longer makes sense to write object files to the same directory as their source. A better solution is to write the object files to a per-firmware directory under a top-level object directory. The top-level object directory can be specified on the command-line with the O= variable, e.g. make O=/tmp/obj. If no top-level object directory is specified an 'obj' directory is created in the top-level of the Syslinux source repository. All the existing make targets continue to work as before, however now they apply to all firmware backends, e.g. 'make installer' will build the BIOS, 32-bit EFI and 64-bit EFI installers and place them under $(OBJ)/bios, $(OBJ)/efi32 and $(OBJ)/efi64 respectively. Note unlike every other bit of Syslinux, the gpxe objects are still kept in the src directory, e.g. gpxe/src, since gpxe is only required by the BIOS backend. It is possible to specify a make target for a specific firmware or list of firmware with the following syntax, make [firmware[,firmware]] [target[,target]] To clean the object directory for just the BIOS firmware type, 'make bios clean' To build both the 32-bit and 64-bit EFI installers type, 'make efi32 efi64 installer' Since the Syslinux make infrastructure is now more complex a new file doc/building.txt has been created to explain how to build Syslinux. The top-level Makefile now exports some make variables for use in module Makefiles, - topdir - the top-level source directory of the Syslinux repository, e.g. /usr/src/syslinux - objdir - the top-level object directory for the firmware backend currently being built, e.g. /obj/syslinux/bios - SRC - the source directory in the Syslinux repository for the module currently being built, e.g. /usr/src/syslinux/com32/libupload - OBJ - the object directory for the module currently being built, e.g. /obj/syslinux/bios/com32/libupload Since we're rewriting the Makefile infrastructure anyway it seemed like a good idea to add parallel support. By writing subdirectories as prequisites for make targets the objects in those subdirectories can be built in parallel. Signed-off-by: Matt Fleming <matt.fleming@intel.com>

* Makefile: Move Makefile fragments into mk/Matt Fleming2011-04-071-1/+2
| | | | | | | | | | | | | | | | | | Move the MCONFIG files into a mk/ directory and give them more descriptive names. This is purely a cosmetic change to make the 'include' directives a bit more coherent by making it obvious exactly which MCONFIG file we're including. For example, in com32/lua/src/Makefile we exchange the line, include ../../MCONFIG for the much more comprehensible, include $(MAKEDIR)/com32.mk Signed-off-by: Matt Fleming <matt.fleming@linux.intel.com>

| | | | | | | | | Use negative pointer values below DGROUP, i.e. for the .payload segment. This makes it a lot easier to figure out if we are dealing with pointers that shouldn't come from where they do, since the DGROUP and .payload segments no longer overlap, and in fact are congruent.

|/ | | | | | | | | | | | | | Additional fixes for the 32K limits in the installers. In the case of the DOS installer, that means changing it from COM format to EXE format (since COM format has a 63K hard limit); retain the name syslinux.com for user compatibility, though (DOS doesn't care what the extension except for pathname search; if it finds an MZ EXE header it will use it.) With the change to EXE means having to handle more than one segment. Since we don't have a real DOS compiler we have to wing it a bit. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

| | | | | | | | | | | | Make the dependency generation more common; have a general pattern in MCONFIG, and use it in rules (not in CFLAGS). For NASM source, in order to stay compatible with old versions of NASM, run NASM twice; newer versions of NASM is capable of generating dependencies simultaneously like gcc can, but that would break compatibility with older distros.

* Clean up embedded Makefile targets; fix build failureH. Peter Anvin2008-08-221-16/+2

* Build _bin.c files in libinstaller; clean up B/I separationH. Peter Anvin2008-06-271-2/+4
| | | | | | | Clean up the BSUBDIR/ISUBDIR separation further. Build _bin.c files, which are an intermediate stage toward building the installers, in the libinstaller directory, since that directory is used by all the installers anyway. That also lets us get bin2c.pl out of the root.
* Move files out of root into core, dos, and utilsH. Peter Anvin2008-05-291-8/+13
| | | | | | | | Move source files out of the root directory; the root is a mess and has become virtually unmaintainable. The Syslinux core now lives in core/; the Linux and generic utilities has moved into utils/, and copybs.com has moved into dos/; it had to go somewhere, and it seemed as good a place as any.
* Assemble via ELF, to enable future linkingH. Peter Anvin2008-05-281-1/+2

* Don't clobber /dev/null when compiling as rootLuciano Rocha2007-05-251-2/+4
| | | | | | Compiling as root is highly discouraged, but some people do it anyway. gcc_ok, however, can clobber /dev/null due to "-o /dev/null"; this is bad. Instead, write a temporary file and delete it.
